RAIL-ANCHOR.

Specification of Letters Patent.

Patented Mar. 29, 1921.

Original application led June 3, 1919, Serial No. 301,428. Divided and this application led July 8, 1920. Serial No. 394,676.

To all whom it may concern:

Be it known that I, OTTO R. BARNETT, a citizen of the United States, residing at Glencoe, in the county of Cook and State of Illinois, have invented certain new and u seful Improvements in Rail-Anchors, of which the following is a specication.

My invention relates to devices for resisting the longitudinal creeping movement of railroad rails, which comprises a yoke member adapted to engage with the base flange of a rail, and a key or wedge member adapted to lclamp said yoke in its operative position, the anchor device being provided with a tie abutment which bea-rs against one of the cross ties during the presence of a creeping pressure onl the rail.

The object of the invention is to provide an improved rail anchor of this character which will be of highest efliciency, simple of design, easy of application to rails having base flanges of differing widths or thicknesses and which will maintain a. firm grip on the rail at all times regardless of whether or not the device is in engagement with the cross tie.

A rfurther object of the invention is to provide a novel yoke member which may be conveniently and Veconomically manufactured from sheet metal and to providel a novel form of key or wedge member adapted to maintain a firm grip of the yoke on opposite edges of the rail base and to take a biting hold on the said base so as to prevent relative movement between the rail and said yoke.

The invention consists of the novel arrangements, constructions and combinations of parts hereinafter described and claimed for carrying out the above stated objects and such other objects as may appear in the following .description of the invention as illustrated in the accompanying drawing wherein,

Figure 1 is a cross sectional view of a rail anchor constructed in accordance with my invention, showing the same applied in its operative position tothe base flange of a rail, said view being taken on line 1-1 of Fig. 2.

Figf2 is Van' end view of the structure Vshownin Fig. 1. Y

Fig. 13 is a detailed view in perspective of the yoke member shown in the preceding figures.

Fig. 4- is a detailed view in perspective of a wedge member preferably employed in connection with the yoke member shown in Fig. 3.

Fig. 5 is an end elevation of a modified form of yoke member. and

Fig. 6 is a fragmentary sectional view showing the serrated end of the wedge in locking engagement with the edge of the yoke shown in Fig. 5..

Like characters of reference designate like parts in the several figures of the drawing.

Referring first to Figs. 1 to l inclusive 10 indicates 'a railroad rail and 11 one of the cross ties on which the rail is supported. The rail anchor shown in these views comprises Va yoke member 12 which extends transversely of the rail under its base flange and embraces opposite edges of the said base and a wedge or key member 13 which holds the yoke in gripping contact with the base flange. The preferred form of yoke is made of sheet metal, consisting of a sheet metal blank having its longitudinal edges bent upward as indicated by numerals 14 in Fig. 3 and is provided at its opposite ends with spaced jaws designated 15-15, 16-16, which seat upon the inclined surfaces of the base flange at points adjacent opposite edges of said base. The jaws are provided with sulciently deep undercuts to permit either pair of jaws to be slipped over one edge of the rail base until the hooked portions of the jaws at the opposite end of the yoke clear the opposite edge of the rail base, whereupon the said j hooked portions may be slipped over the upper edge of the base and into their operative position on the inclined surface thereof. In order to provide a flat surface which will bear firmly on the rail base, the-inner ends of the hooked portions of jaws 15-15, 16-16, are formed with inclined edges 17 corresponding to the inclination ofthe upper surface of the rail base. The body 12 of the yoke is rigidified Y by the upstanding flanges 14 and when in its applied position assumes a slightly inclined lposition with relation to the under of the rail.

tie l1. n order to firmly hold the yoke in its applied position and to prevent relative movement between the yoke and the rail the upper surface of the key is preferably pro- .V vided with a plurality of sharp ridges or corrugations 2O which extend longitudinally of the key and which are adapted to bite into the under surface of the rail base when the key is ldriven home. Preferably the ridges are disposed a-djacent the middle of the key so that when the key .is driven home the said ridges will engage with the central por- 4tion of the rail base and thereby equalize the i gripping action of the yoke on opposite edges of the base. The key may be secured in the yoke by bending the small end of the key downward over the edge 21 of the yoke orl by upsetting the said edge of the yoke so that it will be engaged with the teeth 22 formed on the under surface of the key, 1f desired the end of the yoke may be formed with an extension 23 as shown in Figs. 5 and 6 Vwhich when bent lupward will provide a spring locking tongue adapted to interlock with the teeth 22 of the key. when it is driven to its rail gripping position. It will be obvious, from the abovedescription, that the yoke member shown could be used in connection with other forms of keys and that the form of key illustrated may Ilikewise be employed in connection with other forms of yokes to provide suitable anchor devices without departure from the principles disclosed herein.

It will also be obvious that the specific form of the yoke or key members may be varied without departure from my invention, which contemplates all such changes in form.

I claim:

1. A rail anchor comprising a yoke adapted to extend underneath the rail and pro- Y vided at each end with rail gripping jaws,

and a wedge, having a tie abutting member,

adapted to be place-d in said yoke transversely of the rail underneath the base thereof, said wedgeV having a corrugated surface adapted to bite into the base of the rail when they wedge is driven home. j

2. A rail anchor comprising a yoke adapt- 'ed to extend under the rail and provided at each end with rail gripping jaws,

`and a wedge` having a tie abutting member,

adapted to be placed in said yoke transverselv `of therail underneath the baseV thereof, said wedge having sharp ridges longitudinally of the wedge and adapted to bite into the base of the rail when the wedge is driven home. l

3. A rail anchor comprising a yoke adapted to extend underneath the rail and provided at each end with rail gripping jaws, and a wedge, having a tie abutting member, adapted to be placed in said lyoke transversely of the rail underneath the base flange thereof, said wedge extending through the arms of the yoke and having a corrugated surface adapted to bite into the base of the rail when the wedge is driven home.

4c. l rail anchor comprising a yoke adapted to extend underneath the rail and pro' vided at each end with rail gripping jaws, and a wedge, having atie abutting member, adapted to be placed in said yoke transversely of the rail underneath the base thereof, said wedge having a corrugated surface adapted to engage the base of the rail when the wedge is driven home and means for holding the wedge from slipping backwardly in the yoke. v
